Dave and Kirk are learning about electromagnetic waves in class. Dave says that gamma rays are the most dangerous because they c

ome from outer space. Kirk disagrees. Kirk says that gamma rays are not as dangerous as ultraviolet waves since they cause sunburn. Who is right and why?
Dave is partly right in his answer that gamma rays are the most dangerous, but it is because of their frequency and wavelength, not where they come from.


Neither are right because X-rays have radiation and are the most dangerous. That is why you have to wear a lead vest when you get dental x-rays.


Neither are right. Microwaves are the most dangerous because they have the longest wavelength and the biggest frequency. Microwave kill all living things.


Kirk is right. Ultraviolet waves cause sunburn and that can be very dangerous. Too much sun can cause skin cancer.

I’d say A: Dave is partly right in his answer that gamma rays are the most dangerous, but it is because of their frequency and wavelength, not where they come from.

Gamma rays are the most intense and thus, most harmful electromagnetic waves. Gamma rays radiation poisoning is difficult to shield against. These rays have the most energy and can go through six feet of concrete and damage your DNA as well. The higher the energy waves (gamma, x-ray), the shorter the wavelengths

anzhelika [568]

Answer:

words.hasNext()

Explanation:

Given the code snippet below:

  1.        while (inputFile.hasNextLine()) {
  2.            String word = "";
  3.            String line = inputFile.nextLine();
  4.            Scanner words = new Scanner(line);
  5.            while (words.hasNext()) {
  6.                word = words.next();
  7.            }
  8.            System.out.println(word); }
  9.    }

We have a inputFile Scanner object that can read data from a text file and we presume the inputFile has read several rows of data from the text file. So long as there is another line of input data available, the outer while loop will keep running. In each outer loop, one line of data will be read and assign to line variable (Line 3). Next, there is another Scanner object, words, which will take the current line of data as input. To get the last word of that line, we can use hasNext() method. This method will always return true if there is another tokens in its input. So the inner while loop will keep running so long as there is a token in current line of data and assign the current token to word variable. The word will hold the last token of current line of data upon exit from the inner loop. Then we can print the output (Line 8) which is the last word of the current line of data.
